支柱一般采用型鋼焊接而成，上部用螺栓與支架連接，下部用地腳螺栓與地坪固定。按用途支柱可分為對接支柱和中間支柱，兩標準段支架之間采用對接支柱支承，其余（包括端部）則采用中間支柱支承。支柱的設計一般按受壓柱的穩(wěn)定性來控制。

The pillar is usually welded by the steel type steel, the upper part is connected with the bolt and the support, and the bottom is fixed with the ground bolt and the floor.to the use pillar, it can be divided into the docking pillar and the middle pillar. The two bracket is supported by the docking pillar, while the rest (including the ends) is supported by the intermediate support. The design of the pillar is generally  by the stability of the compression column.

空轉輥道——通常借助軋件重力來推動，所以輥道之平面多做成與水平面之間有斜度，以利用重力作用，因此又稱為重力輥道。一般小型軋機的輥道，特別是升降臺上的輥道，盡可采用重力輥道而不必采用轉動輥道。有些工作輥道的延長部分也有采用重力輥道的。

The idle roller table is usually driven by the gravity of the rolled piece, so the plane of the roller table is made of a gradient between the horizontal plane and the horizontal plane, so as to make use of the gravity effect, so it is also called the gravity roller table. The rolling mill of a small mill, especially the roller table on the lift table, can use the gravity roller without using the rotating roller table. Some of the lengthening parts of the working rollers also use the gravitational roller.

皮帶輸送機的結構參數(shù)的優(yōu)化方法皮帶輸送機的結構雖然受到了種種工況的限制，而輸送機的工作狀態(tài)是處于滿載正常運行的狀態(tài)，在常規(guī)設計計算方法完成后，可以進行采用離散變量優(yōu)化的網(wǎng)絡法，對帶式輸送機參數(shù)進行優(yōu)化設計 。

Optimization of the structural parameters of belt conveyer, the structure of belt conveyer is restricted by various working conditi, and the working state of the conveyor is in a state of full load. After the completion of the conventional design calculation method, the network method of discrete variable optimization can be used to optimize the parameters of the belt conveyor. Chemical design.
