Gray cast iron profiles (square)
Horizontal continuous casting iron bars in a foreign country called dense iron bar (Dense Bars), this material is dense, pressure air tightness, excellent mechanical properties, production rate, low production costs, materials, energy, the sand casting incomparable. Promote the use of cast iron profiles to improve the overall level of industrial machinery, especially to improve the quality of basic pieces, no doubt of great importance. Many foreign industrial countries has been widely applied in various fields iron bars. Mainly used in machine tools, hydraulic and pneumatic, textile and printing and other general machinery, molds, automotive and power, refrigeration and other industries, and these countries in the use of iron bars instead of sand-cast iron, steel, copper alloys and other materials in the process has been and achieved good results.
