Steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron). By far the most widely used material for building the world's infrastructure and industries, it is used to fabricate everything from sewing needles to oil tankers.
The invention will now be further described by way of example with reference to the accompanying drawings. The furnace body 1 is placed on the furnace seat 5, and an inverted conical mold 4 is placed in the middle of the furnace seat 5, and overflow holes 7 are provided on the sides of the furnace seat 5 and the inverted conical mold 4, leaving the side walls of the furnace body 1 There is a

Liquid Phase Sintering. In liquid phase sintering a mixture of two or more powders is sintered at a temperature below the melting point of the high-melting constituent but above that of the low-melting constituent. Liquid phase sintering applies to premixed powders of copper-tin and iron-copper, for example.
bars were compared in the green state and after sintering at different temperatures. The general findings indicate that the product of both the master alloy and pre-alloyed powders exceed the MPIF Standard 35 minimum requirements for sintered density, tensile strength and elongation. Transverse rupture tests of
Together with the high recoveries that are typical of plasma furnace operation, the direct processing of fines enables this type of furnace to compete favourably with submerged-arc furnaces, particularly in the production of ferro-alloys. Some unique advantages of plasma-arc furnace technology for industrial use include the following.
Accelerating quenching vacuum furnace. Accelerating quenching vacuum furnace is mainly used in the melting, rapid quenching or thrown belting process of Rare earth permanent magnets NdFeB, hydrogen storage alloy, nickel base material, high temperature alloy etc. materials under the condition of vacuum or inert gas filling. Accelerati
The present invention discloses a carbon dioxide protection NdFeB sintered molding method for preparing a permanent magnet material, comprising the step of: ingredients, i.e., rejection sheet processing evacuated to 0.05 ~ 0.1Pa heated to 1700 ~ 1800 ℃ Melting 4 to 6 minutes; hydrogen broken milling i.e. vacuum 0.05 ~ 0.1Pa, heated to 100-300 ℃, crushed hydrogen atmosphere pressure 0.8 ~ 1
Molybdenum-copper (MoCu) is a composite material which contains up to 30 percent copper by weight. This composite combines the high thermal conductivity of copper and the low thermal expansion of molybdenum. Our MoCu is perfect for the manufacture of passive cooling elements (heat sinks and heat spreaders) in electronic components.

It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability. Tungsten is practically indestructible. For example, we use this material to manufacture high-temperature furnace components, lamp components and components for use in the fields of medical and thin-film technology.

The Powder Metallurgy (P/M) manufacturing route with pressing, sintering and sizing allows the near net shape fabrication of precision parts made from many different alloy systems. The automotive industry is the most lucrative market for P/M aluminium. However, the low wear resistance, compared
20171020India is the world's number one importer and consumer of stainless steel scrap, according to the Bureau of International Recycling (BIR). This is not only because of the amount of stainless steel produced in India (it is second only to China) but also because of the very high proportion of scrap
75 sintering , the percentage of Fe in the studied alloy is intentionally risen by 1 wt.%. Furthermore, 76 increasing the weight percentage of Fe increases the β stability by rising the Mo equivalent , which 77 can affect the formation of stress-induced products. This study reports on the concurrent formation
----- Sector Notebook Project Iron and Steel Industry In-process recycling of EAF dust involves pelletizing and then reusing the pellets in the furnace, however, recycling of EAF dust on-site has not proven to be technically or economically competitive for all mills.
Ramming Mass Meaning. Ramming mass, also called ramming refractory, is an amorphous refractory lining material for furnace building composed by the refractory aggregate of high alumina, clay, magnesia, dolomite, zirconium or silicon carbide based on the different environmental conditions.
