Mill memorial arch

Product introduction  

Memorial arch, also known as frame, frame body, hot rolling, cold rolling, rolling mill is the important part of, because of the bad mill work environment, in the process of work, roll by bearing frame arch of the larger impact, make the mill housing housing inside the window surface, rack bottom etc appear different degree of corrosion wear and tear,  The clearance between the rolling mill stand and the roller bearing seat exceeds the specified management value.  

The increase of the gap between the rolling mill arch worsens the working conditions of the main drive system of the rolling mill, which makes the main drive vibrate and impact greatly, and the steel ingot is prone to slip when biting, which affects the control of the shape of the plate and greatly affects the quality of the product.  

Highlight the advantages of  

1. Jinjin cast steel adopts Huashu CAE casting simulation software to conduct solidification simulation, analysis and demonstration on the archway according to the initial process to complete the optimization of casting process and ensure that the rolling mill archway has no shrinkage cavity, no shrinkage porosity, compact structure and good comprehensive mechanical properties;  

2. The advanced cast steel adopts metamorphic treatment and argon gas blowing technology at the bottom of ladle to strictly control the quality of liquid steel, reduce the content of gas and harmful elements in liquid steel, improve the purity of liquid steel, so as to ensure the quality of rolling mill arch;  

3. Advanced cast steel adopts special heat treatment, which greatly enhances the wear resistance and impact resistance of rolling mill arch, prolonging the service life of rolling mill arch;  

4. Qianjin Cast Steel has strong production strength of cast steel parts, which can produce and process rolling mill arch and other parts in large quantities, with short casting cycle and large output;  

Strength to ensure reliable quality  

1. After more than ten years of casting practice, the casting team of Qianjin cast steel constantly summarizes experience and makes improvements in the long-term practice.  Now, in the process of casting formed a set of complete and effective principles, namely: adhere to the low-temperature fast pouring principle, to ensure the gradual rise of speed and solidification shrinkage requirements, improve casting quality;  

Advance 2, in the process of rolling mill housing casting, steel casting strictly controls the samples of raw materials, product inspection, quality assessment, such as work, and equipped with Germany OBLF GS1000 vacuum direct reading spectrometer, high-speed carbon sulfur analyzer, digital ultrasonic flaw detector, multi-purpose magnetic powder flaw detector and other physical and chemical testing facilities, each piece of products for nondestructive flaw detection,  Don't let any defective products leave the factory;  

3, Qianjin cast steel has many years of casting experience and strong mechanical processing capacity, can provide customers with a series of services and complete solutions from blank casting to finished products processing
