Embodiment Construction

[0006] A vacuum lost foam casting cast steel coating, which is composed of water, sodium bentonite, suspending agent, organic binder, corundum powder, and additives; the coating is made of the following components in weight percentage: 30% to 45% water , Sodium-based bentonite 2-5%, suspending agent 1-4%, organic binder 2-4%, corundum powder 50%, auxiliary agent 0.2-1%.

[0007] The configuration process of the special coating for vacuum lost foam casting cast steel coating is as follows:

[0008] (1) Coating configuration equipment

[0009] The coating equipment is an important factor for the quality of the coating configuration. The coating configuration is generally a secondary stirring, that is, a process of high-speed stirring to fully mix the paint; secondary stirring is a process of low-speed stirring to exhaust the gas in the paint. .

[0010] (2) Coating configuration process

[0011] After the raw materials are purchased, they should be carefully checked and teste...

Abstract

A cast steel coating for vacuum lost foam casting comprises components in percentage by weight as follows: 30-45% of water, 2-5% of sodium bentonite, 1-4% of a suspending agent, 2-4% of an organic binding agent, 50% of emery powder and 0.2-1% of an aid; the performance of the cast steel coating for vacuum lost foam casting depends on composition, a preparation technology, an application technology and a drying technology of the coating. With the adoption of the coating, defects such as recarburization, air holes and the like of cast steel pieces are overcome, the coating is stable in comprehensive coating performance, low in coat and ideal in effect, and the comprehensive product percent of pass of the vacuum lost foam cast steel pieces can be ensured to be higher than 97%.

Description

technical field [0001] The invention relates to the technical field of vacuum lost foam casting, in particular to the production of a vacuum lost foam casting cast steel coating. Background technique [0002] Vacuum lost foam casting is a new process developed in recent decades. With its unique advantages, it makes the casting production process look brand new. This green casting process adopts the assembly process of modules, which reduces the process links, improves production efficiency, improves product quality, reduces energy consumption, reduces manufacturing costs, improves the working environment, realizes zero pollution emissions, and reduces Therefore, it is widely used in the production of gray iron castings at home and abroad. At present, the production of cast steel paint for vacuum lost foam casting is complicated and the production cost is high. Contents of the invention [0003] In order to overcome the defects of the prior art, the object of the present ...
