Cause analysis of slag hanging in spa-h steel quality cutting process

At the same time, the company operates a variety of products of related iron and spa-h steel quality steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained spa-h steel quality ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.

41Cr4 (1.7035) material is an alloy structural steel grade commonly used internationally. Its tensile strength, yield strength and hardenability are all higher than that of 40# steel, but it also has certain defects that its weldability is limited and there is a tendency to form cracks. 41Cr4 steel is generally used for more important quenched and tempered parts, such as parts that work under alternating loads, medium speed and medium load parts.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from spa-h steel quality. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

Manganese steel plate is a kind of common steel, which is a kind of high-strength anti manganese steel. spa-h steel quality, Manganese steel plate is mainly used to bear the impact, extrusion, material wear and other severe working conditions. It is a typical anti-wear steel, with austenite and carbide as cast structure. After water quenching at about 1000 ° C, the structure changes into single austenite or austenite with a small amount of carbide.

GB/T 1591-2008 Q460E material is a high strength low alloy steel plates. Q460E steel product size spa-h steel quality: 3*1500*5900, 4*1500*6000, 48*3130*10100, 47*2610*8450, 3*1500*6000, 6*2000*8000, 48*2880*8550, 48*3130*10400, 5*1500*4150, 10*2000*8000, 48*2610*8700, 48*3170*10800, 5*1500*6000, 8*2000*2800, 47*2600*7000, 48*2880*3900, 16*2160*3300, 8*2000*8000, 47*2610*8700, 48*3150*10700, 5*1500*6000, 48*3130*10400 (mm).

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, spa-h steel quality and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
