Show bright foundry production of investment casting to the process design of these vessels accessories, recommended materials, the use of recommended information are described in detail.
china’s foundry industry energy consumption than that of Japan 2 times
High energy consumption, high pollution, I do not know since when has become synonymous with the domestic foundry industry. On a global scale, although the domestic casting production no doubt become a world power, but the profits generated by the foundry industry is not comparable to Japan, the United States and other countries. The reason for this contrast, the addition to the finished product prices low energy issues, as well as part of the reason from the domestic foundry industry. Incomplet...
Auto parts industry breakthrough
Enforcement Division of the General Administration of Quality Supervision, Inspection and Quarantine on the 13th afternoon again interviews with representatives of Volkswagen (China) Investment Co., Ltd., as soon as possible to take effective measures to solve the problem of Volkswagen DSG gearbox failure. The person in charge of the Enforcement Division of General Administration of Quality Supervision, Inspection and Quarantine said that since the period of time, the General Administration of Q...

High alloy steel
High alloy steel began about half of the nineteenth century. 1883 British Hadfield (R0.A0.Hadfield) first obtain a high manganese steel of the patent, has been 100 years of history, high manganese steel is a high content of carbon and manganese content of the high alloy steel, this with a hundred year old steel, because of its large impact abrasive wear conditions, when used with a strong work-hardening capacity, while both good toughness and ductility, and easy to grasp the advantages of the pr...
Cast high-alloy steel
In the casting of high-alloy steel, adding a total of 10% of alloying elements (mass) or more alloying elements can be added one, two, or more species. Contains large amounts of alloying elements in steel, the organization has been a fundamental change. Makes the use of steel with special properties, such as ωMn = 13% of the austenitic high manganese steel with high impact wear performance, and if ωcr = 18%, ωNi = austenitic stainless steel, with good resistance to Rot and so, therefore, is actu...
Low-alloy steel casting
In machinery manufacturing, a common low-alloy steel casting including manganese, chromium and nickel three series. The series is in the casting of steel based on the composition of carbon steel casting alloy and heat treatment by phase to in order to obtain a higher temperature than the cast steel, mechanical properties, in various types of engineering machinery parts, precision casting of large-scale use. 1) Mn low-alloy steel With manganese as the main alloying elements, and silicon, molybden...
Carbon Steel Casting
A country that has adopted the carbon content of steel is used as the standard classification. Table 1 lists the national standards of carbon steel casting, on the steel grades, chemical composition and mechanical performance requirements, grades of “ZG” said Steel, followed by numbers indicate the weight fraction of carbon steel, the nominal value, to the very few that. Impurities in steel casting according to their level of phosphorus and sulfur content and is divided into three le...
three type of intensity for investment casting shell
Shell quality should meet the strength, permeability, thermal expansion, thermal shock, thermal chemical stability, thermal conductivity, shelling and other performance requirements. Strength Shell strength is the most important and basic performance, the difference in the investment casting process stage the strength of three different indicators, namely temperature strength, high temperature strength, residual strength. 1. Temperature strength Smooth shell temperature strength wet strength mea...
Sand Casting Brief
According to statistics by sand casting priority Casting production in all, 60 ~ 70% of sand casting is produced, and about 70% of which is clay sand production. Mainly due to sand casting and low cost compared to other casting methods, production process is simple, short production cycle. So as the car engine cylinder block, cylinder head, crankshaft, etc. are used for green sand casting process production. When the wet type can not meet the requirements and then consider the use of clay, sand ...
Precision casting tolerance
High size precision casting, generally up to CT4-6 (sand casting for the CT10 ~ 13, casting for the CT5 ~ 7), of course, the investment casting process complex, dimensional accuracy of castings are many factors, such as mold material shrinkage, melting mode of deformation, shell in the process of heating and cooling the amount of change in the line of the alloy during the solidification shrinkage and deformation in the casting, so the size of an ordinary precision castings though high, but still...
