Investment casting joints

In the production process of mining machinery water glass casting production process, to complete the clean production, should do the following.

1. effective flue gas emission and purification equipment should be configured in the electric furnace and other forging heating furnace and furnace outside the solution station.

2. moderate purification treatment material should be carried out before blending and firing.

3. process exhaust gas (volatile phenol. Acid mist. Triethylamine, etc... Effective exhaust purification equipment.

4. According to the amount of sewage discharge. Select the appropriate and effective remediation methods and establish the corresponding sewage treatment equipment.

5. Timely testing: set up monitoring points at pollutant discharge ports (points) and timely testing of key pollutant discharge values in accordance with legal and regulatory requirements to ensure standard discharge and continuous improvement.

6. Production of investment mold precision casting impeller and environmental protection equipment are not running bubbles. Drip. Leakage state, noise key production stations and transmission paths equipped with sound insulation. Sound absorption. Single or integrated control equipment.

Carbon, silicon, manganese, sulfur and phosphorus are the five major elements in cast iron. Carbon and silicon are the two basic chemical molecules in ordinary gray cast iron. They have a key influence on the organization and properties of cast iron. The organization and properties of ordinary gray cast iron are controlled and improved by controlling and adjusting the content of carbon and silicon.
