Small factory enterprise heat treatment solution

  There are many small factories, enterprises and even home workshops in the production process, especially the hardware industry, which involves heat treatment processes. They do not understand the heat treatment industry and equipment. The process details are not clear and limit the development of enterprise factories.   In particular, how to reduce production costs in the current market downturn, and deal with some simple processes of heat treatment outsourcing. In this regard, Chengchi will share relevant content with practitioners in the heat treatment industry.

  There are many heat treatment processes, such as: normalizing, annealing, solutionizing, aging, quenching, tempering, annealing, carburizing, nitriding, tempering, spheroidizing, brazing, etc. Need to be based on process, output, product. Determine the size of the enterprise; artifacts, quantity (capacity), process.   Then to determine the type, specification, quantity and process layout of the heat treatment furnace. Also consider electricity, energy, environmental protection, transportation, delivery methods, etc.

  The most basic type of heat treatment furnace is the box furnace: because the box furnace has a wide temperature range, low equipment cost, and many types of processes, such as quenching, tempering, annealing, solid solution, aging and even etc. The basic heat treatment process can be done with a box furnace.   Depending on the working size and the temperature used, the box furnace price ranges from several thousand yuan to ten thousand yuan. If the process is not complicated and the requirements are not high, a box furnace can solve the heat treatment work of a small factory.

  Followed by the pit furnace: the pit furnace has less energy consumption, less space, low thermal insulation performance and low cost. It is the first choice for small and medium-sized enterprises for heat treatment.   It can be used for heating, tempering, annealing, carburizing, nitriding, aging, solid solution, tempering, spheroidizing and other processes. In particular, pit furnaces are preferred for vacuum furnaces and atmosphere furnaces. Because the lower half of the pit furnace is below the ground, it is necessary to build a tunnel for infrastructure. It also needs to be equipped with a crane or crane to reduce the work intensity.

  Quenching tank: When there is quenching heat treatment process, it needs to be equipped with quenching oil tank and quenching water tank. The more common concrete sinks have lower construction costs. It is easy to use, usually on the same line as furnaces such as quenching and solid solution, which is convenient for crane lifting.

  Once again used is the oven: low temperature heat treatment process can be carried out through the oven. The oven equipment has low cost and low operating cost. Treatment and drying can also be used for low temperature tempering, solid solution and other processes.

  Other furnace types can choose trolley furnace, atmosphere furnace, vacuum furnace, etc. according to process requirements, product characteristics, output, etc.
