Although the jaw crusher has the lowest crushing and wear cost, it is common for a set of tooth plates to survive for more than 100 hours, even tens of hours, in hard, strong abrasive materials such as granite and basalt. Quartzite and corundum is more only ten hours or even hours. In addition there are some strict control of the amount of metal grinding debris industry, such as refractories, electronic glass and other industries due to the high magnetic properties of non-magnetic steel can not be removed by magnetic separation equipment, resulting in excessive iron pollution can not be applied. Therefore, the development of a high wear resistance and magnetic properties of wear-resistant material tooth plate has become a need, so high chrome jaw platewill come into being.
As we all know, in most abrasive wear conditions, high-chromium cast iron is now the best overall performance and the use of cost-effective materials, and thus as a composite material used to resist wear and tear that part of the material, high chromium cast iron is preferred. As for the large flat-panel castings under strong extrusion, only a non-high-manganese steel is required due to the high toughness reserve, so a composite high chromejaw plate is conceivable the spline is divided into rack and Substrate in two parts, the rack is made of hard high-chromium cast iron, substrate with excellent toughness of high manganese steel. But the problem is that the jaw plate is a typical flat castings, surface area, thickness is small, whether it is inlay package composite casting or two-liquid bimetallic process is more difficult, and even a composite out of one High-quality jaw blank, the heat treatment is an insurmountable level, high manganese steel and high chromium cast iron a very flexible, a very hard and brittle, both are extremely mechanical properties of materials. Although the high-chromium cast iron quenching temperature and high manganese steel is similar, but high manganese steel in order to obtain excellent microstructure, heated after the need for rapid cooling in cold water. Because the high manganese steel billet is not very quenched before quenching, this time the impact toughness is often less than 10J / cm2, and once through the water quenching toughness can reach 150J / cm2. The high chromium cast iron because of their great brittleness, hardness after quenching is greatly improved, but in the quenching process of thermal stress and phase transition stress can easily make the casting cracking, so quenching process design requirements is reached quenching Performance requirements at the same time, as far as possible the use of low quenching cooling rate, professional said to reduce the quenching intensity. So high-chrome cast iron is generally cooled in the air, thicker wall thickness can be used to add air-cooled blower approach, but also the use of oil quenching process, which is often not because of high chromium cast iron added or less can be strongly enhanced hardenability Of the valuable elements of molybdenum, as a last resort.
Our engineers based on years of production experience, the high chromium cast iron rack and groove to make the first high-manganese steel substrate to complete the first heat treatment independently, the specially designed high-chromium tooth root evenly coated with high-strength adhesive, and then inlaid High manganese steel substrate in the groove, everything has been specially designed and sophisticated control, to be dry, you can install the machine to use. However, due to the excellent rheological properties of the high manganese steel, the specially designed high chromium cast iron racks have been in the groove of the high manganese steel substrate for over 10 hours Work, the matrix of metal rheology filled into the specially designed gap, the high chromium cast iron rack was high manganese steel substrate firmly wrapped together. This solves the problem of two different properties of the composite material on the tooth plate.
