1.Scope of Application
Hot sawing machine is a kind of cutting equipment widely used in the production line of section steel in metallurgical plants, especially in the rolling production line of profiled section section steel, which is generally installed on the production line behind the rolling mill. Its main function is to cut the head, tail and length of the rolled piece rolled by the rolling mill. Compared with other cutting equipment, the hot saw has the advantages of simple equipment, light weight and high production efficiency. In many cases, the production of the whole rolling workshop is often affected by the limitation of the production capacity of the hot saw.

3.Product Introduction
There are many types of hot saws, which can be divided into sliding seat type and four-bar type in terms of structure; According to its layout in the operation line, it can be divided into fixed sawing machine and mobile sawing machine; According to the main transmission form, it can be divided into motor direct transmission type and belt indirect transmission type; It can be divided into three types according to the transverse movement: fixed type, sliding plate type and roller type; According to the sawing form, it can be divided into four link type and rack type.
NHI Co., Ltd. designed and developed a circular sawing machine Φ 1100㎜～ Φ 2000㎜。 The sliding seat type hot saw developed by our company, the saw blade and its transmission device are installed on the upper sliding table. The structure of the saw blade has small lateral vibration, high efficiency, large stroke, good process performance, complete and compact structure, and has been widely used. Another kind of four-bar hot sawing machine. The saw blade feeding mechanism is a four-bar mechanism. Because its feeding mechanism is rolling friction, it is not easy for sawdust to fly in. This feeding mechanism ensures that the saw blade is basically fed horizontally. Its advantages are large process and good process performance, so it is also suitable for large sawing machines and has been widely used in recent years. The hot sawing machines of different specifications designed by our company have reasonable structure, convenient operation, safety and reliability, and are welcomed by the majority of users.
