Excellent price low mill archway Henan Qianjin made

product presentation

Archway, also known as frame, frame, is an important part of hot rolling, cold rolling, rolling mill, due to the mill working environment, in the process of work, the roller through the bearing seat rack arch caused larger impact, make the mill frame arch inside window face, rack arch bottom appear different degrees of corrosion wear, lead to the mill frame and roller bearing clearance more than the management value.

The rolling mill arch gap increase aggravates the working condition of the main drive system of the rolling mill, makes the vibration impact of the main drive is large, and the steel ingot is easy to slip when it bites into it, which affects the control of the plate shape and greatly affects the product quality.

outstanding advantages

1. Qianjin cast steel adopts CAE casting simulation software to simulate, analyze and demonstrate the memorial arch according to the initial process, optimize the casting process, and ensure that the cast mill memorial arch has no shrinkage hole, no shrinkage loose, compact tissue, and good comprehensive mechanical performance;

2. Qianjin cast steel adopts deterioration treatment and argon from the bottom blowing technology to strictly control the quality of the steel liquid, reduce the content of gas and harmful elements in the steel liquid, improve the purity of the steel liquid, so as to ensure the quality of the mill arch;

3. Qianjin cast steel adopts specific heat treatment methods, which greatly enhances the wear resistance and impact resistance of mill arch, and extends the service life of mill archway;

4. Qianjin casting steel has strong production strength of steel casting parts, and can carry out large-scale production and processing of rolling mill archway and other parts, with short casting cycle and large output;

Strength assurance, reliable quality

1. After more than ten years of pouring practice, the casting team of Qianjin Steel has continuously summarized the experience and improved in the long-term practice.Now, in the process of pouring has formed a set of complete and effective principles, namely: adhere to the principle of low temperature fast pouring, ensure the gradual rising speed and solidification shrinkage requirements, improve the casting quality;

2, in the process of mill arch casting, forward casting steel strictly control the raw material sample detection, product inspection, quality assessment, and equipped with German OBLF company GS1000 vacuum direct reading spectrometer, carbon sulfur high-speed analyzer, digital ultrasonic flaw detector, versatile magnetic particle detector and other physical and chemical testing facilities, for each factory product nondestructive testing, do not let any defective products factory;

3. Qianjin Casting Steel has many years of casting experience and strong machining ability, which can provide customers with a series of services and a complete set of solutions from blank casting to finished products;
