Material: cast iron plate using HT200-300 casting, material ingredients ingredients and ingredients according to the following criteria (%): carbon: 3.1-3.4, manganese: 0.6-0.9, silicon: 1.5-2.0, sulfur <0.12, phosphorus < 0.3. Hardness> 180, the second tempering treatment.

Cast iron plate It is specially designed for the flattening of large equipment with reasonable design, stable structure, high precision and abrasion resistance. It can be used for flattening from 3000mm to 6000mm. The product is made by scraping or grinding. Measurement, and grinding of machining centers, tool shops, machine shops, inspection and maintenance workshops, large-sized equipment bases, measuring chambers and precision machining, and accurate measurement and inspection of the flatness, flatness and angle tolerance of workpieces. .

This product is used in resin sand casting process, the appearance of smooth and no flaws, beautiful. Reasonable ingredients by calculating the proportion of raw materials by adding the appropriate, is the hot metal to meet the national standard, hot metal test to ensure high iron Can make the molten iron to achieve a good cast performance.Use of high quality new iron, clean scrap.
Second, the company's cast iron plate casting:
(1) casting large bags, small bags, be sure to dry baking, wet bag will be used in the use of fire roasted, non-iron hot iron instead of drying.
(2) pouring principle: slow - fast - slow, when pouring pouring sprue pouring can not be cut off, this is to prevent the interface into the gas.
Third, the mold shape The company uses a sub-surface has a stomata, dark chamber, in the mold on the dark chamber is to reduce the pressure.
Cast iron platform by the model of national standards of production, special-shaped, thickening, can also be customized according to manufacturers needs.
Four. Cast iron plate material:
(1) The hardness of the work surface is 200.
(2) high-quality high-strength gray iron 250, after 600-700 degrees high temperature annealing, so that casting durable, heat treatment is to reduce the gradual internal stress, improve the surface hardness and wear resistance, precision and stability Strong.
6. Surface treatment:
(1) non-working surface to remove sand and coated with anti-rust paint.
(2) the face of the use of artificial scraping process, this work is very important, scraping master in the work to know the space, three-dimensional, flat, parallel, vertical basic concepts.
(3) to reduce the proportion of the work of how to use the proportion of interpolation to rough scraping to reduce the number of measurement and installation to improve efficiency.
