Hot sawing machine is widely used in steel metallurgical plant, especially for special section steel rolling production line as cutting equipment, generally mounted at the back of rolling mill production line, functioning in head or tail cutting and fixed length cutting on rolled piece of the rolling mill. Compared with other cutting equipment, hot sawing machine has more advantages such as simple structure, light weight and high efficiency etc, In many cases, the entire steel rolling workshop production is often affected and limited by hot sawing machine production capacity
 
Hot saw machine is sorted in plenty kinds, in structurally available with slide seated and four-bar linked two categories, upon arrangement in the production line is divided into stationary saw cutting machine and movable saw cutting machine According to the main transmission form can be divided into motor-direct passing type and belt-indirect transmission type; depending on transverse form can be divided into three kinds, as fixed type, slide plate type and trolley type, based on sawing form can be divided into four-bar linked and toothed bar type etc.
 
The disc cutting machine NHI designed and developed has 50 years of history. Our company has developed a disc saw machine with sawing blade diameter ranges from Φ1100 ~ Φ2000㎜. The slide seated hot saws that NHI developed and researched, where the blades and gear mounted on the sliding deck, resulting in small transverse vibration on the blade, of high efficiency, large travel journey and good process performance, compact structure, and widely applied. Another kind of machine as four-bar linked Hot Saw, that the sawing blade feeding mechanism is a four-bar linkage, due to features in rolling friction, not easy to fly sawdust, and ensure the blade feeding along as horizontal, taking the advantage of large stroke, and good process performance, suitable for large-scale cutting machine, in recent years has been widely applied. the different specifications hot sawing machine that NHI designed, features in reasonable structure, easy operation, safe and reliable, welcomed deeply by users.
