Design, fabrication and installation of tilting, gas fired and electric stationary crucible furnaces. Available in various configurations. Features vary depending upon model, including nozzle mix burners, low pressure combustion air blowers, heavy rod type nickel chromium elements, chamber temperature controls, ceramic fiber hearth plates and redundant circuits.
Common machining is done to produce furnace components such as stranded and other wires, sintering and annealing boats or evaporator coils. In the lighting industry, molybdenum-lanthanum oxide is used for example for retaining and feed wires.
The carbon / carbon composites(we also named it as C-C composite or carbon-carbon composite material) is the carbon fiber and its fabric reinforced carbon matrix composites. It is one of the few alternative materials currently used in more than 1650 °C, the highest theory temperature is higher than 2600 °C, so it is considered to be one of
Althrough the wide applications of graphite tube,it's also important to use fairly,know the service-life of graphite tube,replace graphite tube timely,make sure the authenticity and reliability of research results.we can estimate the service-life from the following several points:
Answer. Vacuum permanent-mold casting is a form of low-pressure casting in which a vacuum is used to draw molten metal into the cavity. Vacuum molding is sand casting in which the sand mold is held together by vacuum pressure rather than by a chemical binder. 11.7 What are the most common metals used in die casting? Answer.
Rods & Shapes Stiffness Affordability Tight Tolerances Wide range of "small" sizes Pultruded products perform incredibly well in bending and tension (pulling) applications since all the fibers are oriented along the length of the tube (or rod).

Tungsten has the highest melting point of all the refractory metals, a low coefficient of thermal expansion and a relatively high density. Tungsten's good electrical conductivity and excellent thermal conductivity are further valuable properties. The values of all these properties are higher for tungsten than they are in the case of molybdenum.
The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less.
The process of heat treatment involves the use of heating or cooling, usually to extreme temperatures to achieve the desired result. It is a very important manufacturing processes that can not only help the manufacturing process but can also improve product, its performance, and its characteristics in many ways.
vacuum annealing oven. The tempering furnace is used for tempering general metal parts in air and for quenching, annealing and aging heat treatment of aluminum alloy die castings, pistons, aluminum plates and other light alloy parts. The shell is welded with steel plate and shape steel plate, and the trolley is welded with shape steel and shape
Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials.
Ceramic Fiber Products. Ceramic Fiber Blankets; Ceramic Fiber Modules; Ceramic Fiber Boards; Calcium Silicate Boards; Ceramic Fiber Papers; Vacuum Shaped Ceramic Fibers; Bulk Ceramic Fiber; Special Shaped Refractory. Custom Shaped Refractory Bricks; Custom Size Refractory Plates; Heating Element Holder Bricks
The basic raw material for steel manufacture is either the hot metal from the blast furnace, steel scrap or a mixture of both. The proportions of material used vary according to the process and the type of steel required. Steel can be described in general terms as iron with most of the carbon removed, to make it tougher and more ductile. There
