Abstract
The invention discloses a method for decomposing and rolling a granite alloy saw blade by utilizing a steel rail, which is realized by the following steps: the method comprises the following steps: the waste steel rails are placed in order and cut into sections; step two: the radian of a rolling cylinder in the rolling machine is adjusted, so that the radian of the rolling cylinder is gradually expanded from the initial end to the tail end; step three: putting the steel rail cut into a section shape into the initial end of a roller press, and dividing the rolled and broken steel rail into two sections, namely, one section is arranged at the top and the middle part of the steel rail, and the other section is arranged at the bottom of the steel rail; step four: the top and the middle of the steel rail are sent into a forging machine to be made into hexagonal steel, and the bottom of the steel rail is sent into the forging machine to be made into a saw blade. The rolling cylinders are utilized to roll the steel rail gradually, the top and the middle part of the steel rail are one section, the bottom part of the steel rail is the other section, the steel rail can be divided into two sections by one-time rolling, each section can be reused, the steps are simplified, and meanwhile, the efficiency and the cost are effectively improved.
Description
Technical Field
The invention belongs to the technical field of steel rail decomposition, and particularly relates to a decomposition and rolling method for manufacturing a granite alloy saw blade by using a steel rail.
Background
In the prior art, steel rails are main components of a railway track, the steel rails can be disassembled and replaced after being used for a period of time, and the replaced steel rails are mostly returned to a furnace for smelting and recycling. The replaced rail can be used for producing a cutting saw blade, namely a saw blade for cutting granite.
At present, in the process of producing the saw blade by using waste steel rails, the steel rails are cut into three sections in a cutting mode, namely the top, the middle and the bottom of the steel rail are respectively cut into three sections, the top is used for producing hexagonal steel, the bottom is used for producing the saw blade, and the middle is subjected to low-price treatment.
Therefore, the traditional cutting mode causes obvious limitation to the product produced by recycling the steel rail.
Disclosure of Invention
The invention aims to solve the technical problems that the traditional decomposition mode influences the specification of a final product and generates waste in the prior art, and provides a method for decomposing and rolling a steel rail for manufacturing a granite alloy saw blade so as to overcome the defects in the prior art.
The invention is realized by the following technical scheme:
the invention discloses a method for decomposing and rolling a granite alloy saw blade by utilizing a steel rail, which is realized by the following steps:
the method comprises the following steps: waste steel rails are placed in order, cleaned and cut into sections according to a specified length;
step two: the radian of a rolling cylinder in the rolling machine is adjusted, so that the radian of the rolling cylinder is gradually expanded from the initial end to the tail end;
step three: putting the steel rail cut into a section shape into the initial end of a rolling machine, gradually pressing the steel rail by a rolling cylinder to break, and dividing the broken steel rail into two sections, namely, the top and the middle of the steel rail are one section, and the bottom of the steel rail is the other section;
step four: and (3) conveying the top and the middle of the steel rail into a forging machine to prepare hexagonal steel, and conveying the bottom of the steel rail into the forging machine to prepare the saw blade.
The steel rail cutting machine is reasonable in structure, the traditional steel rail is cut into three sections, namely the top of the steel rail is the first section, the middle of the steel rail is the second section, the bottom of the steel rail is the third section, the two cutting processes are needed, the operation process is complicated and repeated, and the middle section cannot be reused and is relatively serious in waste. The existing cutting mode is rolling, namely, a machine utilizes a rolling cylinder to roll the steel rail gradually, the top and the middle part of the steel rail are one section, the bottom part of the steel rail is the other section, the steel rail can be divided into two sections by one-time rolling, each section can be reused, the steps are simplified, and simultaneously, the efficiency and the cost are effectively improved, so that the steel rail is fully reused.
