6061 aluminum alloy is a kind of deformation aluminum alloy which can be strengthened by heat treatment. Because of its good weldability and excellent comprehensive mechanical properties, 6061 aluminum alloy is widely used in automobile, shipping, packaging and other industries. For some 6061 aluminum alloy components with complex structure,...
42crmoh steel belongs to medium carbon alloy structural steel, which has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low temperature impact toughness. Therefore, 42crmoh steel is designed for diesel engine transmission shaft....
The process statistics are as follows: (1) There were 14 cases of L-type engine block and 36 cases of V-type cylinder block; (2) There were 12 cases of HT200 engine block, 28 cases of HT250 engine block and 10 cases of HT250 cylinder block; (3) The distribution of cylinder...
As a key part of engine, cylinder block casting is one of the difficulties in engine production. The design level of gating and riser technology is an important condition to determine the quality and performance of engine production. The engine performance requirements are strict and there are many specifications....
There are many kinds of cast iron parts for engine block. The main classification methods are the number of cylinders and the arrangement of cylinders. According to the number of cylinders, there are mainly single cylinder and multi cylinder engine block. Four cylinder, six cylinder, eight cylinder and sixteen...
Working conditions of ICP inductively coupled plasma spectrometer The working conditions of ICP ICP ICP spectrometer are: high frequency power, atomizer pressure, atomization efficiency (pump speed), integration time (exposure time), etc. Considering the small interference effect and strong and stable analysis strength, the working conditions of the instrument are...
1 Sample weight If the boron content in ferroboron is high, the sample weight is too small, the weighing error will increase; if the sample weight is too much, the reagent addition amount will increase correspondingly, and the sample is not easy to dissolve completely, and the overflow may...
Boron (element symbol b) is a rich element in China. Boron is often known as the vitamin in steel. Trace boron can significantly improve the hardenability of steel and save a lot of expensive alloy elements with strong hardenability, and greatly improve the wear resistance of metal materials. Boron...
Ductile iron piston is mainly used in medium speed diesel engine. It is the key component of diesel engine. It needs to bear high compressive stress and thermal alternating load when working, and its working condition is very bad. Because the piston works at high temperature, metal parts are...
Compared with the traditional casting, the precision forming technology of digital dieless casting, which uses the sand mold as the cavity or sand core, does not need wood mold and metal mold. It has the advantages of less pollution, short cycle and low cost, and has become an important...
