Wear-Resistant High Temperature Resistant Slag Pot Mining Special
Transfer Equipment
Product Definition
This product is a load-bearing device whose sole purpose is to
collect molten or solid slag resulting from metallurgical or
chemical processes, retain it during transport and deposit it at a
disposal site. Slag pots are an essential component of lifting
equipment and therefore must comply with the national safety
regulations of the country in which they are used in terms of
mechanical design, engineering and operation. Dillinger slag pots
are designed for use in the European Union and comply with the
requirements of the European Machinery Directive 2006/42/EC: each
slag pot carries the CE conformity mark.
Material
The pot body is made of cast steel DICAST, a ZTIC brand for casting
products: the material is similar to steel grade A27/A 27M grade
65-35 (April 2003), BS 3100 A1/A2 steel grade (January 1991) or DIN
17182 steel grade GS 20Mn5 (May 1992). DICAST is a fully killed
steel, vacuum degassed and processed to a fine grain structure with
increased toughness and elongation.
Apart from supplying the trunnion forgings and designing the
moulds, all other processes are carried out in the company's
in-house foundry.
Moulding is carried out individually in modular flasks using a
resin-bonded sand mould process.
Trunnions, if present, are preferably cast: they are usually made
from steel S355 J2G3, but can also be supplied as cast or
hot-fitted. Melting is carried out in an oxygen steelworks (two
180-tonne BOF converters); the ladle capacity allows a continuous
bottom pouring process with permanently controlled pouring speed.
Metal composition analysis is checked using a computer-connected
spectrometer.
Heat Treatment
Each casting pot undergoes a composite quality heat treatment
(annealing) aimed at grain refinement and stress relief, namely:
- Heating to above AR3 temperature, austenitizing at about 915°C
and controlled cooling in the furnace
- Holding between 600°C - 630°C and cooling to 300°C in the furnace
for finishing furnace cleaning and trimming
The inner surface is specially treated to completely remove surface
defects that may cause slag adhesion. In addition, the castings are
shot peened for descaling and the outside is additionally coated
for transportation.
The surface quality is derived from the manufacturer's
comprehensive practices and meets the requirements of MSS
SP-55-1996 (Visual Evaluation Method for Surface Irregularities).

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. |
