High Temperature Resistant Slag Pot Thickened Lining For Mining And Metallurgy
High Temperature Resistant Slag Pot Thickened Lining For Mining And Metallurgy
Materials
The pot body is made of DICAST cast steel, a ZTIC trademark for casting products. This material is similar to grades A27/A 27M, grade 65-35 (April 2003), BS 3100 A1/A2 (January 1991), or DIN 17182 GS 20Mn5 (May 1992). DICAST is a fully killed steel that is vacuum degassed and processed to a fine-grained structure, resulting in increased toughness and elongation.
Heat Treatment
Each pot undergoes a combined heat treatment (annealing) to refine the grain size and relieve stresses:
- Heating to a temperature above AR3, austenitizing at approximately 915°C, and controlled cooling in the furnace.
- Holding between 600°C and 630°C, followed by cooling in the furnace to 300°C. The furnace is cleaned and finished. The inner surface is specially treated to completely remove surface defects that could cause slag adhesion. In addition, the castings are shot blasted for descaling and given an additional coating on the exterior for shipping.
Surface quality is the result of the manufacturer's thorough practices and complies with the requirements of MSS SP-55-1996 (Method for the Visual Assessment of Surface Irregularities).
Quality Assurance
Manufacturing processes adhere to the requirements of the implemented ISO 9001:2000 quality system.
Standard documentation ensures full traceability of each process step:
Manufacturer's test certificate in accordance with DIN EN 10.204 § 3.1, covering chemical composition, mechanical properties, and non-destructive testing;
Dimensional inspection with accompanying "as-built" drawings;
High-quality heat treatment records;
Documentation required by Machinery Directive 2006/42/EC (where applicable).

Product Parameters
| Manufacturing Except the supply of the forgings for trunnions and the engineering of the pattern, all further operations are carried-out at the in-house foundry plant. |
| Moulding the castings are manufactured in a workman-like manner as required in the China standard DIN EN 1599-1: August 1997, ruling the delivery conditions ofcastings. The moulding is individually carried out within a modular flask by using a sand preparation based on resin bonding. |
| Trunnions the trunnions - when any - are preferably cast-in:they are as a rule manufactured from the steel material S355 J2G3 to DIN EN 10250-2: December1999 and forged as per DIN 7527 February 1975. Cast-on or hot-fitted trunnions can be also provided. |
| Melting the melting is carried out in the oxygen steel plant ( 2 off 180 t BOF converters ); the ladle capacity allows a continuous bottom pouring process the speed of which is permanently controlled. The metal analysis is checked by using a computer linked spectrograph. |
