1. Since the horizontal continuous casting process can obtain a relatively dense matrix structure, the oil pressure resistance and air tightness of horizontal continuous casting profiles are higher than other engineering materials. It can be said that the use of horizontal continuous casting profiles to make hydraulic parts is an ideal material so far . In addition to high production rate and low production cost, it also has better machining performance than steel. This is because in the cutting process, the cutting resistance is reduced due to continuous chipping.

2. In the machine tool manufacturing industry, horizontal continuous cast iron profiles are used to manufacture milling machines, grinders, drilling machine tables, machine tool guides, bearing seats, etc. The production cost is significantly reduced, and the machined surface has particularly uniform high strength performance and hardness indicators. Due to its good machining performance, horizontal continuous cast iron profiles can be used to make various mechanical rotating parts and various special-shaped parts, such as flanges, rings, V-belts, plungers, etc.

3. The rolling piston in the core of the rolling piston air conditioner compressor is the main sliding part. In order to increase the compressor displacement and increase the pressure of the compression chamber, the manufacturers will inevitably lead to increased wear between the friction pairs. To ensure the reliability of the compressor, the research and application of the compressor manufacturers such as the American POTOREX company, the American FEDDERS company, the Japanese HITACHI company, the South Korean LG company, and the Chinese Zhuhai Gree Group show that the continuous cast iron profile is the material for manufacturing rolling pistons. Through quenching, continuous cast iron bars can easily reach a hardness above HRC50 to achieve their excellent wear resistance.

4. The high-speed wire rod rolling into the production line conveying stick parts suitable for Morgan’s technology in the United States. After being used by Baosteel, Shagang and other iron and steel companies, it has been well received. Now it can completely replace the imported parts from the United States. The situation that the parts after the wire need to be imported from abroad.

5. According to the requirements of the Ministry of Railways to increase the speed of trains, the ADI bushings on passenger (cargo) car bogies processed from continuous cast ductile iron profiles require austempered HRC38-48, σb>= 1200MPa,δ>=1%, unnotched impact energy (=<40 degrees Celsius ak>=35J/cm2) crush strength>=2000MPa. It is used after evaluation and demonstration by experts of the Ministry of Railways, and it has been officially put into use on locomotives.
