Abstract
The invention relates to a method for alternatively mixing resin chromite sand and resin quartz sand, comprising the steps of preparing equipment, preparing raw materials, matching, debugging the equipment, setting parameters, controlling and the like. The method has high equipment utilization ratio, and one sand-mixing machine plays a role of two sand-mixing machines, thus saving one sand-mixing machine and a whole set of other equipment and devices matched with the sand-mixing machine, and saving the cost by more than 500, 000 yuan. The method avoids the occupied area of a set of equipment, has simple and convenient operation and omits the trouble that the moulding sand of one of the two sand-mixing machines needs to be carried, and the time used in the carrying process.
Description
Technical field
The present invention relates to the method for a kind of resin chromite sand and resin quartz sand alternatively mixing system.
Background technology
In recent years, lifting along with technical capability, product structure is constantly changing, the high value-added product size of order increases year by year, large-scale Vertical Mill, autogenous tumbling mill, semi-autogenous mill, the occupation rate of big aircraft project etc. is in continuous expansion, make that the structure of foundry goods is more and more complicated, for organization of production and technological design have increased difficulty, some casting structure complexity, clearance hole is little, can't finish with original water-glass sand production cleaning, using resin sand is the unique channel that addresses this problem, but consider heavy section steel castings (casting thickness is all more than 100mm) making mud core, can not solve super-huge steel-casting molten steel infiltration problem equally if use single resin quartz sand to make the mud core, if using single resin chromite sand price to hold again can't stand, optimal scheme is to use resin chromite sand bag resin quartz sand, usually the mixed system of these two kinds of molding sand needs two complete equipments just can finish, and for resin sand as special sand, only make the producer that part mud core uses, it is luxurious that two complete equipments just seem, its subject matter is: the available machine time is limited, and utilization rate of equipment and installations is low; Floor space is big; Core box is with two kinds of core sands, two equipment mullings, troublesome poeration (wherein a kind of core sand must a dead lift to the residing position of core box, and need manually join in the core box); Increase a set of equipment, cost more than at least 50 ten thousand.
Summary of the invention
The present invention is problems such as utilization rate of equipment and installations is low, floor space big, troublesome poeration, cost height for solving, and the method for a kind of resin chromite sand and resin quartz sand alternatively mixing system is provided.
Technical scheme of the present invention: 1. preparation machine: select for use one to satisfy the fixedly liftable continuous muller of production requirement and other supporting devices; 2. raw material is prepared: select chromite sand and quartz sand, weighing proportion, and the weight of calculating and the isopyknic chromite sand of quartz sand respectively changes into the productivity ratio of equipment; Select alkali phenolic resins and supporting alicyclic organic curing agent for use; 3. proportioning: do the addition test of roughing sand, resin and curing agent respectively with Orthogonal Method, determine best proportioning; 4. equipment debugging: press the flow of puddle mixer, productivity ratio is divided into third gear, i.e. one grade of 10t/h chromite sand, second gear 18t/h chromite sand, third gear 12t/h quartz sand; 5. parameter is set: roughing sand flow and corresponding resin, the curing agent proportioning different according to above third gear, the Reasonable Parameters of setting resin, catalyst pump; By setting requirement, respectively roughing sand, resin, curing agent to be carried out for 20 seconds and weigh, the correctness that certificate parameter is set by repeatedly revising parameter, reaches the optimised process design object according to deviation; 6. control: the various parameters that are provided with realize by control button, reach the purpose that different preparing process use under different situations, and realize the purpose of resin chromite sand and resin quartz sand alternatively mixing system.
Beneficial effect of the present invention: the utilization rate of equipment and installations height, a puddle mixer has played the effect of two puddle mixers; Saved a puddle mixer and supporting a whole set of other apparatus, save cost more than 50 ten thousand yuan; Avoided the floor space of a set of equipment; Easy and simple to handle, exempted and used trouble that two wherein a kind of molding sand of puddle mixer must carry and used time in handling process.
