铸钢

With the development of modernization, the demand on abrasive cast steel has been increasing.

随着现代化建设的发展，对耐磨铸钢的需求不断增加。

With annal capability of80000 t molten steel and10000 t steel casting, our company can make full use of vacuum refining furnaces, large size heat treatment furnaces and heavy duty rough machining equipments, our developing aim is to make larger size, more precision and specialized products.

我厂具有年产8万吨钢水、万吨铸钢件能力，充分利用真空精炼、型热处理炉、型粗加工装备，产品向做大、精、专方向发展、大的一次钢水量268吨，最大生产锻造钢锭143吨。

The truck cast steel three big piece type bogie is easy to maintain. But since the grate weight under spring and the large operation strength during running, it is difficult for the bogie to keep the positive position. The critical speed of the snaking motion is low, which is inapplicable for high speed running. The other type of truck bogie is H type integrative truss. Its structure is complicate relatively, which is not easy to manufacture and maintain. But it can keep the positive position of the bogie preferably. And because it is adopted the structure of axle box one series elastic suspend, the weight under spring reduces. Which achieve the effective control to wheel sets and improve the running quality of the bogie distinctly.

货车铸钢三大件式转向架便于制造维修，但因其簧下质量大，在运行中轮轨作用力大，转向架难以保持正位，蛇行运动临界速度低，不适用于高速运行；货车转向架的另一种形式是"H"型构架一体式，结构较为复杂，不便于制造和检修，但它能够较好地保持转向架的正位，而且由于采用了轴箱一系弹性悬挂结构，降低了簧下质量，实现了对轮对的有效控制，明显地改善了转向架的运行品质。

A effective process of purification treatment of high silicon cast steel melted by MF induction furnace was obtained.

得到了中频感应电炉熔炼高硅铸钢的有效钢液净化工艺。

The carbon content of mild steel is much lower than cast-steel.

软钢的含碳量要比铸钢的低得多。

Velan is one of the world's leading manufacturers of industrial valves, supplying forged and cast steel gate, globe, check, ball, butterfly, knife gate and engineered severe service valves for critical applications in power, chemical and petrochemical, oil and gas, pulp and paper, mining, marine, cryogenic and general construction industries.

Velan是世界工业阀门行业主要的制造商之一，提供锻钢和铸钢闸阀、截止阀、止回阀、球阀、蝶阀、刀闸阀和适用于关键部位的工作强度繁重的工程阀门，适用于电力、化工和石化、油气、纸浆和造纸、矿业、船舶、低温和普通建筑行业。

Valve product range is not entirely uniform, some by object (such as chemicals, oil, power stations, etc.), some by the media (such as water vapor, air valve, etc.), some on the material (such as cast iron valves, steel valves, valve Steel, etc.), Hydraulic control valve some by connecting shape - points (such as the thread, flange valve, etc.), some on the temperature (low temperature valve, high temperature valve, etc.).

阀门产品的种类繁多，说法也不完全统一，有的按用途分、有的按介质分、有的按材质分（如铸铁阀、铸钢阀、锻钢阀等）、有的按连接形式分、有的按温度分。

A locomotive is designed to be almost indestructible — in this case, a 160-tonne construction of cast and welded steel. Each piece must be taken out by hand with blowtorches. The breakdown will happen from the top down in three steps.

这列火车头是由一百六十公吨的铸钢制造而成，每块铸钢都要用焊枪精准地拆解开来，拆解方式由上而下，分为三个步骤。
