SCALGUN-WS

(For Removal of Water Scale Deposits, Cleaning Boilers, Heat Exchangers etc.)

 DESCRIPTION:                                                                                                                

SCALGUN-WS is an inhibited acidic composition formulated for rapid removal of water scale deposits in the heat transfer equipments, condensers, economisers, evaporators, water tube boilers, compressors, etc.

PROPERTIES:                                                                                                                 

It reduces maintenance cost and is more efficient than mechanical or hand cleaning.  It also reduces labour requirements.  SCALGUN-WS can reach those corners and crevices where manual or mechanical cleaning is impossible.  The removal of scale allows heat transfer to take place more readily as small deposits of scale cause insulation with a resultant heat loss.

 

Normally the scale left from water in heat transfer equipments is composed of Calcium or Magnesium carbonates, Sulphates, Phosphates, Silicates and Iron Oxide.  SCALGUN-WS dissolves the majority of these deposits and insoluble constituents are loosened sufficiently to allow the deposits to be flushed off.               

APPLICATION:

There are two simple methods of using SCALGUN-WS for cleaning equipments, pipes, tubes etc. either circulation or soaking, however circulation is most effective.  It is added @ 10 % concentration to the equipment as the water is running into the system to be treated.  If necessary, the solution can be heated to 50°C for rapid action.  However higher temperatures of more than 60°C should be avoided. Post descaling the equipment should be flushed thouroughly with water.

SCALGUN-WS has been approved by major air-conditioning O/E suppliers and very widely used in most fertlizer plants and refineries, since last 5 decades.

ASHTREAT-660 is a neutral Hardening salt which has no tendency to decarburise steel.

 

Hot melt bath at about 800-900 °C is used for heat treatment of various carbon and alloy steels. It is very suitable for heat treatment of parts which have already been carburised and then selectively machined.


Procedure :

ASHTREAT-660bath can be easily made up by weighing the required quantity of salt and placing in a furnace fitted with special mild steel or heat resistance alloy pot or in a ceramic lined electrode type furnace. Salt is melted and further heated at the operating temperature. Parts are inserted in completely dry and clean condition and allowed to remain at that temperature for about 5 to 30 minutes for small size components and 1 to 2 hours for large size components depending upon the thickness and volume of the articles. If the salt bath is covered with a ASHTREAT-Additive layer it can be worked upto 1000 °C.


Maintenance :

Every day, the sludge collected at the bottom of the pot should be removed and fresh ASHTREAT-660 be added to raise the bath to normal working level. In order to regenerate the bath, small addition of about 0.5% of FEROSIL may be added to the heated salt bath. This periodic oxidation of the bath should be carried out once a shift, in order to keep the bath in neutral condition.

Note :

For the Heat Treatment of Stainless Steel or cutlery, equal parts of ASHTREAT-660 and ASHTREAT-960 may be made up and used in the range of 900-1100 °C. In these baths any carbon layers should not be used since the stainless steel components will suffer loss in corrosion resistance due to absorption of carbon.


Packing : 50 Kgs.

ASHCARB-P80 (Pack Carburising Compound)

(For Case Hardening Of Steel)

Case Hardening Of Steel

There are great many articles for which it is of vital importance that the surface hardness should be as high as possible and the wear resistance as great as practicable and that they should possess at the same time a fairly high impact strength, such articles include some kinds of gears, cams, eccentrics, wheels, etc.

Parts that are required to have a high corrosion resistance or high resistance to scaling at elevated temperatures  may be manufactured either of acid resistant alloy steels or of a  plain low carbon steel which is then subjected to an appropriate case hardening (chemical thermal) treatment to increase its resistance to  corrosion  or  scaling.

To increase the surface  hardness and wear resistance of machine parts the machine manufacturing industry employs  carburising, nitriding, cyaniding treatments which are commonly termed as "case hardening processes".

Case hardening of steel  consists in saturating the surface of a hard steel with carbon, nitrogen and certain  alloying elements, such as aluminium,  chromium, silicon. All these elements are  diffused in the steel at elevated temperatures.   the solubility of  all these elements in iron  increases with a rise of  temperature.   maximum solubility of carbon in alpha iron is about 0. 02% at 723°c whereas  in gamma iron 0. 8% carbon can dissolve, and 2% at a temperature of 1130°c.

Carburising process with Ashcarb-P80 (pack carburising)

The object of  carburising is to produce as hard a surface resistant to wear and other mechanical forces. It consists of  saturating the surface  layer of a steel article  with  carbon.

Articles subjected to  carburising are usually manufactured of low carbon steels such as  0. 2 to 0. 25% of carbon contents. Carburising process should be adjusted so as to obtain carbon content of 0.8 to 0.9%  and not more than 1%.  with higher carbon content, the surface layer becomes very  brittle because a coarse cementite net work is formed on it. In industry two methods of carburising are  mainly used ie. Pack carburising (with solid carburisers) and gas carburising (in contact with  carburaceous  gases). pack carburising :

Articles to be carburised  are packed in close containers ie. Pots or "boxes" completely surrounded with solid Ashcarb-P80. The  packing operation requires care to  ensure that sufficient compound is used to supply the carbon required.   No parts,  should contact the sides of  tinpots.  The distance between parts to be carburised as  packed should be not less than 20 to 25 mm. The containers are covered after slightly  tamping of carburising salt  and all the openings are luted with clay in order to prevent the air from penetrating into the pot.

ASHTREAT-960 heat treatment salt gives excellent results for final hardening temperature for high speed steels. liquid carburising salts. ASHTREAT-960 can be used for hot die steel, high carbon, high chrome non-shrinking die steel. At present about 90% of the high speed tools are being hardened in salt bath and because it requires furnace for pre-heating for which we recommend you to use our ASHTREAT-540 or ASHTREAT-670 and a high temperature furnace for super heating. We recommend you to use our salt ASHTREAT-960.

 

The furnaces required for this stage of treatment : Most economical one is electrodes type furnace. The pot of these furnace should be made out of fire bricks and fire clay or silica. The electrodes-the best one is 25% chrome 2% nickel steel or 18/8 stainless steel, but for economy purpose, low carbon steel or mild steel also can be used.

 

In the super heat furnace the high speed components are kept for shorter time to avoid oxidising and decarburising. The temperature control in this stage is most important it should not be higher than the specified temperature for the salts. If it is taken on the higher side, it will not only spoil the components but will spoil the complete bath as well. For controlling the temperature, radiation pyrometer can be used or controlled pyrometer with compensating lead wire and thermocouple should be platinum-rhodium 10-13% type.

 

After every charge of the bath, if the furnace is tilting type, the liquified salts can be drained out and should be preserved for re-use, or if the furnace is fixed type, the salts will remain in the pot and the same can be reused by starting the furnaces. In this case only fresh salt should be added to maintain the level of the bath.

 

The time factor for the salt bath dipping can be decided by technician according to the job. But it is a common practice being a high temperature bath, the time should always be calculated in seconds however, general practice is to keep 30 seconds to maximum 7 minutes.

 

The soaking time depends as per cross section of the components, it should be kept 20 minutes per sq.inch in preheating bath of ASHTREAT-670 or ASHTREAT-540.
