Exothermic welding technology is internationally renowned, and the quality of exothermic welding molds is guaranteed to be first-class and reputable
Exothermic welding
Whether the technology is qualified is a key part of testing your construction and normal use in the later period. Reasonably control the exothermic fusion welding is a very important part. Good products must have good technology to coordinate the construction. Botou Xinyongtai Lightning Protection Equipment Co., Ltd. has many years of field experience in exothermic welding and can easily solve various complex exothermic welding problems. For difficult problems, we specialize in exothermic welding, fire mud welding, exothermic welding powder, and exothermic welding molds
. We have a professional team responsible for free training and inspection, which can completely solve all your problems. Exothermic welding is a very simple, high-quality, and efficient metal welding technology. Mainly used in key projects such as railways, highway power plants, substations, switching stations, high-voltage transmission lines, electrified railways, telecommunications, mobile communication base stations, microwave relay stations, radar stations, ground satellite receiving stations, and some other valuable precision instruments and computers. Computer room equipment, postal and telecommunications program-controlled equipment, radio and television equipment, electronic medical equipment, etc. are used for work grounding and protective grounding of oil transportation pipelines and oil and gas tanks, and lightning protection grounding for flammable and explosive material warehouses.
Exothermic welding mold
Precautions when using
First, draw a suitable mold according to the shape and size of the connector, and configure the corresponding type of solder powder
, Pull before welding Process the parts to remove oil, dirt and oxide layers
, apply sufficient strong heat to the exothermic welding mold
, install the mold and inspect it, then pour the solder powder and ignite the reaction
/>, clean the exothermic welding mold and prepare it for next use
Exothermic welding is a simple, efficient and high-quality electrical connection process. It uses the exothermic reduction reaction heat of metal oxides as a heat source. In the cavity of the special mold, a fused joint of a certain shape and size that meets the connection requirements is completed. The exothermic welding mold consists of an exothermic flux, a welding mold, and a mold operating mold clamp to form a welding system. Traditionally, people call it hot melt welding, hot melt flux, fire clay, etc.
Principle of use of exothermic welding mold
The principle of exothermic welding is to use the high-temperature molten metal conductor produced during the chemical reaction (combustion) of the welding agent to achieve the purpose of welding. The reason for using this method is because the chemical reaction is very fast (it only takes a few seconds to generate extremely high heat, and it can be conducted to the welding part very quickly. There is no need to use any other heating source, so if it is applied to the connection of metal conductors, Is the best method.
Exothermic welding mold
Exothermic welding must be completed using a special casting mold. This casting mold is made of graphite that is high temperature resistant and has half the permanent strength. This mold can easily withstand the ultra-high temperature when metal is melted.
The mold is composed of several parts, including mold cavity, mold cavity, injection hole, etc. This mold has different shapes of links, such as straight-through, T-shaped, cross type, etc. The shape, size of the mold cavity and the flow direction of the molten metal are all carefully designed and manufactured. The completed connector has a beautiful and consistent appearance. The quality of the exothermic welding mold is unmatched by other connectors.
Advantages of exothermic welding in facilities
★Simple equipment, easy to carry, no external heating source required, suitable for outdoor and indoor on-site soldering operations.
★Fast soldering speed, saving manpower and material resources . (The time for soldering and mold cleaning should not exceed minutes)
★The soldering method is simple and easy to operate, and no technical welding workers are required.
★The joint shape is uniform and the quality control is easy. (Only by visual inspection Yes)
★The total heat added is much less than other welding methods, and it has little impact on the damage to the insulation.
Maintenance of Xinyongtai exothermic welding mold
The exothermic welding mold must be Clean both ends of the rail frequently, align the unit and true, the distance between them should be around millimeters, and the gap between the welding rail ends before the molten steel is poured into the mold weld, this will ensure consistent results. The time from the start of the work is typical The time a train runs on the track, up to more than an hour, depends on the size, environment and temperature of the railway, about minutes. The entire installation process is to let the objects to be welded cool. Exothermic welding mold
Removal and cleaning of the weld heat Chiseling and grinding produce a smooth combination. Around the ends of the rail, two or three hardened sand molding sheets are clamped with a torch of suitable heat capacity, which is used to preheat the ends of the rail and the inside of the mold. A refractory crucible is placed on top of the metal with The alloy has the right amount of thermite and the rail has reached a sufficient temperature to ignite the thermite to allow the reaction to complete. The reaction crucible is then dug into the bottom of the exothermic welding mold.
Exothermic welding technology Internationally renowned, the quality of exothermic welding molds is first-class and the reputation is guaranteed
