Our company's A633Gr.D as-rolled material power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the A633Gr.D as-rolled material utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
A514 steel plate is high strength weldable steel quenched and tempered according to ASTM standard. ASTM A514 steel plate is mainly used in places where A633Gr.D as-rolled material high tensile strength and high yield are required. The lifting gears of engineering vehicles, and racks for offshore platforms generally use A514 grade Q or A514 Gr Q. The A633Gr.D as-rolled material hardness of A514 steel plate is between 235-290. A514 steel yield strength is more than 630MPa, and tensile strength is more than 700MPa. A514 steel plate is difficult to process. In the United States, the use of A514 steel plate is very large.
Carbon steel is easy to be forged and processed into other products. Alloy steel and other steel products require too much investment for later processing equipment, and the processing is relatively cumbersome. In addition, the use of carbon steel has a long history, and people have rich experience to operate carbon steel, A633Gr.D as-rolled material. It is more handy for the operation and processing of carbon steel. In addition, carbon steel has a wide range of adaptability, from the sea to the land. No matter high temperature or severe cold, the stability of carbon steel is always very reliable.
The wear-resistant plate has the main advantages of high strength and hardness, good toughness, A633Gr.D as-rolled material high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of A633Gr.D as-rolled material wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.
The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. A633Gr.D as-rolled material, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.
The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
