The utility model discloses an auxiliary tool for workpiece linear cutting machining, which comprises a mounting frame, a support frame and a molybdenum wire, a wire storage box is arranged on the mounting frame, a guide wheel I is arranged on one side of the mounting frame, a guide wheel II is arranged on the mounting frame, a guide wheel III is arranged on the mounting frame, a guide wheel IV is arranged on the mounting frame, and the molybdenum wire is arranged on the support frame. The first guide wheel and the second guide wheel are located on the same horizontal plane of the upper end of the side wall of the installation frame, the supporting frame is arranged on the installation frame, four fifth guide wheels are arranged on the supporting frame, and the molybdenum wires are wound around the first guide wheel, the second guide wheel, the third guide wheel, the fourth guide wheel and the fifth guide wheels respectively. According to the auxiliary tool for workpiece linear cutting machining, the four fifth guide wheels are additionally arranged, the motion trail of the molybdenum wire is changed to complete machining of special workpieces, the heights of the supporting plates are changed, the heights of the guide wheels can be adjusted to adapt to workpieces of different sizes, the tension of the molybdenum wire is conveniently adjusted, the situation that the machining precision of the workpieces is reduced due to the fact that the tension of the molybdenum wire is large or small is avoided, and machining efficiency is improved. The product quality is influenced.

This utility model discloses an improved rotary kiln for efficient reduction of iron-containing waste slag. It includes a feed hopper (1), a feed screw conveyor (2), a flue hood (3), a kiln body (4), a kiln body support roller device (5), a kiln body transmission device (6), a kiln body baffle roller device (7), a discharge end sealing cover (8), a kiln inner wall insulation layer (9), a heating spray gun (10), and a discharge screw conveyor (11). Based on the characteristics of the roasting raw materials and the process characteristics of high-temperature reduction roasting, the feed and discharge ends of a conventional rotary kiln are modified to be airtight. During roasting, a sealed space is formed inside the kiln. The kiln body insulation layer is constructed with a spiral-shaped refractory brick layer to increase the reducing concentration inside the kiln and the dispersion of materials during movement, achieving efficient reduction. After the application of this improved rotary kiln, low-cost, high-efficiency reduction roasting is achieved.
