Abstract
The invention discloses a composite stirring wing material of mortar stirring and conveying machinery. The composite stirring wing material comprises the following component by weight percent: 0.25 to 0.35 part of C, 1.30% to 1.50% of Mn, 1.00% to 1.50% of Si, 1.00% to 1.50% of Cr, 0.25% to 0.35% of Mo. 0.05% to 0.15% of Ti, less than 0.03% of S, less than 0.03% of P and the balance of Fe. The composite stirring wing material is used for solving the problems in the prior art that the stirring wing material is low in safety and reliability because the fatigue fracture invalidation of the stirring wing material is easily generated due to the fact that the stirring wing material is hard and brittle. The composite stirring wing material disclosed by the invention is excellent in mechanical performance parameters and matched with new material selection, so that the product preparation difficulty is lowered; and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of stirring wing materials, in particular to a stirring wing composite material of a mortar stirring and conveying machine. Background technique [0002] The stirring wings in the vehicle-mounted bottom mortar mixing and conveying mechanism bear the surface friction and impact fatigue caused by the alternating load of mortar during work. This working condition requires that the stirring wings must have the following functional indicators: (1) The surface hardness is high to adapt to the wear-resistant working environment; (2) The product structure is dense, and the core has appropriate toughness to adapt to the impact of alternating loads. This can overcome the impact fatigue fracture of the product caused by the material brittleness brought about by high hardness. [0003] The main parameters of the existing stirring wings are: unit weight 3.60Kgs / piece; main wall thickness 15mm; outline main dimension 300...
