Grass flour raw materials are selected from crop straws and pastures that do not contain toxic substances, such as corn stalks, sorghum stalks, cereal grass, peanut skin, bean straw, alfalfa, sand sorghum, clover, red bean grass and other pastures.
The mechanical selection is to use a sieve crusher capable of crushing the straw into 1 cm. The various raw materials are preferably comminuted separately, that is, the gramineous plants and the legumes are separately pulverized to prepare the feed in proportion.
The method is to mix the corn stalk grass powder and the glutinous rice powder by 3:1 (the grass powder is preferably mixed with warm water at 40 ° C in winter), and then the mixed grass powder is piled up in a place with a higher temperature in the fermentation chamber, and piled up into 30- 50 cm thick square pile, insert a thermometer, cover the sack, straw mat, plastic cloth, or cover a layer of 3-6 cm thick grass powder to maintain its temperature and humidity; the temperature inside the pile reaches 50 ° C, fermentation needs 1 -1.5 days, when the smell of wine is smelled, the fermentation is successful. At this time, the grass powder is soft, cooked, hot and fragrant; the indoor temperature should not be lower than 5 °C, and the stove should be placed in the winter; the humidity of the grass powder should be grasped by the hand. It is advisable to sew water without dripping. After each fermentation, some fermented grass powder should be left as the primer for the next fermentation. The fermented grass powder is added with 0.5 kg of salt and 0.5 kg of bone powder per 100 kg, and is blended with appropriate cornmeal, bran, bean curd, and carrot. After mixing, the sheep can be directly fed.
Stainless Steel Pipe is a kind of hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also used for furniture, kitchenware, etc. The hardness of stainless steel pipe is usually measured by Brinell, Rockwell and Vickers. Annealed stainless steel pipe with inner diameter of more than 6.0 mm and wall thickness of less than 13 mm. Production process of stainless steel seamless pipe A. round steel preparation; b. Heating; c. Hot rolling perforation; d. Cutting head; e. Pickling; f. Grinding; g. Lubrication; h. Cold rolling; i. Degreasing; j. Solution heat treatment; k. Straightening; l. Pipe cutting; m. Pickling; n. Finished product inspection. Common materials are 201, 304 and 316.ETC
