Investment casting mounts

Casting production is a molding process of metal parts blanks with certain shapes, sizes and characteristics, from smelting metal, manufacturing metal type casting will molten metal poured into the metal casting. Solid and gaseous waste and harmful gases will be discharged in this process.

In terms of environmental protection, the casting process has various provisions.

First, to improve the company's clean production level.

The actual classification into clean production levels.

Level I: advanced level of international clean production.

Level II: Advanced level of domestic cleaner production.

Level 3: Basic domestic clean production level.

According to the specific situation of the company, the company should improve the level of clean production as much as possible after meeting the product quality regulations and cost regulations, the following points.

1. Reduce the energy consumption in the melting process

Induction medium frequency induction furnace is the key to the equipment selected for pig iron smelting; the foundry company should reduce the kinetic energy consumed by melting tons of metal liquid in order to reduce the impact on the environment.

2. Improve process productivity

Melting process of investment mold precision casting parts metal yield is directly related to the energy consumption per unit weight of casting.

3. Reduce pollutant emissions

Pollutant production index (before tail solution) is the production of pollutants in the production (or processing) process per unit of product, including the amount of sewage production, waste gas production solid waste production (before tail solution).

The pollutants emitted during the casting of different alloys vary greatly and can be divided into dust, smoke and hazardous waste. For these three indicators, the casting company should reduce the net weight of pollutants produced by the production unit of heavy casting to reduce the impact on the environment.

4. Increase the proportion of old sand regeneration

In the production process of investment mold precision casting furnace bar, whether clay wet sand or resin sand casting, due to ineffective clay, broken sand, will produce a large amount of ineffective soot, affecting the performance of the molding material. The direct and simple method of the above problem is to fill the new sand and discard the old sand.
