High wear resistance, high hardness and good toughness are important indexes of bimetal composite pipe, which are directly related to the service performance of pipe fittings. The wear resistance of the inner layer of 304 stainless steel outer layer and high chromium cast iron inner layer centrifugal cast composite...
The quality of bimetallic composite pipe has always been the focus of research, and its bonding interface directly affects its performance. By improving the distribution of the transition layer and increasing the thickness of the transition layer, the bonding strength between the wear-resistant layer and the base can be...
As shown in the figure, it is produced with the help of computer simulation φ 400mm and φ Rough finished products of 580mm centrifugally cast cylinder liners. It can be seen that the horizontal centrifugal casting of cylinder liner has complete mold filling and good forming quality, which verifies...
The figure below shows the simulation results of the pressure field distribution of molten metal at the completion of pouring. In the process of horizontal centrifugal casting, the distribution of pressure field is basically concentric when the molten metal just fills the mold. The magnitude of pressure is directly...
As a key structural member in mining, metallurgy, coal, electric power and other industries, the composite seamless pipe is just opposite to the working surface of the composite roll. Its working surface is the inner surface. The manufacturing principle roughly includes two aspects: the base layer (outer layer) should...
Figure 1 shows the simulation results of temperature field in the process of filling, solidification and cooling of liquid metal during horizontal centrifugal casting of super large cylinder liner. It can be seen that the liquid metal moves forward in the form of laminar flow after entering the mold,...
Man28-33d wet cylinder liner is selected as the research object. The blank length of cylinder liner is 686mm and the diameter of inner hole is φ 265mm, the diameter of the outer circle is φ ３５２～３９０ｍｍ。 Figure 1 shows the blank drawing of cylinder liner centrifugal casting drawn by...
Figure 1 shows the simulation of velocity field of molten metal. It can be seen from figure 1A that the molten metal spreads to both sides at the inlet. When the filling time is 30s, the direction of liquid flow can be tracked, which shows that the liquid metal...
Engine is the power source of automobile and ship, and cylinder liner is one of the core components of engine. The cylinder liner is embedded in the cylinder barrel of the cylinder block, the inner hole has a piston for reciprocating motion, and the cylinder head is pressed on...
The working surface of the composite roll is the outer surface, that is, the outer layer should meet the requirements of high hardness and high wear resistance, and the inner layer should have good toughness. The combination effect of centrifugal casting determines the mechanical properties of the composite roll,...
