The moulds of slope protection bricks are manufactured by the cooperation of steel moulds, cement and vibration platforms. The concrete is loaded into the steel moulds and vibrated on the vibration platform for about 10 seconds. The moulds are taken out after the cement solidifies and removed when there is a little water left in the moulds, so that the complete cement slope protection bricks are successfully manufactured and formed. Beautiful appearance, lightweight, easy to construct, above can also design different patterns, according to customer requirements to produce different text and patterns.
护坡砖模具保养比模具维修更为重要,模具维修的次数越多,其寿命越短.而模具保养得越好,其使用寿命就会越长.每次使用后要及时清理模具里面的混凝土残渣,保持模具内壁干净,模具内壁的光滑度是脱模的关键,而水泥具有很大的摩擦力,所以平时我们要用光滑剂多喷涂在模具内壁,延长它的使用寿命.
Mould maintenance of slope protection brick is more important than mould maintenance. The more times the mould is maintained, the shorter its service life is. The better the mould is maintained, the longer its service life will be. After each use, the concrete residue in the mould should be cleaned up in time, the inner wall of the mould should be kept clean, and the smoothness of the inner wall of the mould is the key to demoulding. Cement has great friction, so we should spray more smoothing agent in peacetime. Apply it on the inner wall of the die to prolong its service life.
护坡砖模具的化学成分,晶粒度,纯净度,碳化物以及夹杂物等的数量、形貌、尺寸大小以及分布情况,还有护坡砖模具的热处理制度和热处理后得到的金相组织等因素都对钢的韧性带来很大的影响.特别是钢的纯净度以及热加工变形情况对于其横向韧性的影响更为明显.钢的韧性、强度与耐磨性往往是相互矛盾的.因此,要合理地选择钢的化学成分并且采用合理的精炼、热加工以及热处理工艺,以使模具材料的耐磨性、强度还有韧性达到佳的配合.
Chemical composition, grain size, purity, quantity, morphology, size and distribution of carbides and inclusions, heat treatment system and metallographic structure after heat treatment of slope youle.89ix.comhuatiw.89ix.comzuhehuati.89ix.comguandao.89ix.comhuanwanggui.89ix.com
peidiangui.89ix.comprotection brick mould have great influence on the toughness of steel. Especially, the purity of steel and hot working deformation have more obvious influence on its transverse toughness. The toughness, strength and wear resistance of steel are often contradictory. Therefore, it is necessary to select the chemical composition of steel reasonably and adopt reasonable refining, hot working and heat treatment processes so as to make the wear resistance, strength and toughness of die materials match well.
