Abstract

The invention discloses a rock drill steel tube blank heating system. The rock drill steel tube blank heating system comprises a feedback device, a propelling device, a locating device, a heating device, a heating device, a temperature measuring device and a conveying device. The distances d1 and d2 between three flame heaters are controlled through the feedback device. The heating temperature offlame injectors is controlled through an oxygen distribution box and a fuel gas distribution box. On the other hand, the invention further comprises a rock drill steel tube blank heating method. Through a gradient flame heating roll-forming method, the compactness of a rolled part is controlled, the rock drill steel internal defects caused by the same deformation of uniformly heated tube blanks inthe prior art are avoided, the quality of rock drill steel is improved, and the service life of the rock drill steel can be prolonged. The radial temperature of the rock drill steel tube blank is accurately controlled through the feedback device. Through flame heating, the cost is low, just one set of the flame injector of which the size is matched with different sizes of rock drill steel tubes needs to be designed, and other devices are all universal assemblies without replacement.

Description

technical field [0001] The invention relates to the field of brazing steel blank heating, in particular to a heating system and a heating method for brazing steel blank. Background technique [0002] Brazing steel, commonly known as brazing steel, plays a key role in rock drilling and blasting. Whether it is the mining of mineral resources or the construction of infrastructure such as railways and highways, drilling and blasting operations are inseparable, and the use of brazing steel is inseparable. Due to the harsh working environment of the brazing steel, the brazing steel is easily damaged, so improving the quality of the brazing steel and prolonging its life has become the top priority of the brazing steel research. The density of the brazed steel billet gradually decreases from the outside to the inside, so the internal performance of the brazed steel billet is worse than that of the outside. [0003] In the manufacturing process of brazing steel, the brazing steel b...
