Compound grease sand core production method for producing electric thermo-couple cast iron protection tube casting parts

Номер: CN0101480702B
Принадлежит:

The invention discloses a core-making method adopting synthetic-oil sand for producing a casting of a thermoelectric couple cast-iron protecting tube, which comprises the following steps: firstly, synthetic oil is taken as binding agent, casting roughing sand belongs to refractory aggregates which are mixed to produce core sand, and then, the core sand is taken as raw materials to be respectivelymade a mandril and a core mark, and the mandril and the core mark are finally assembled together to form a sand core, wherein a core box 1 used for manufacturing the mandril is of a longitudinal split steel-made tubular structure, and a whole-box roasting process is adopted when the mandril is manufactured; and a core box 2 used for manufacturing the core mark is a steel-made core box. Invention lowers the production cost while simplifying the production process; in addition, the quality of the produced sand core is good, and the finished product ratio is high.

Thermal couple protector tube processing technique

Номер: CN0101195151A
Принадлежит:

The invention relates to a process for producing protecting pipes of thermocouples, which is composed of three parts of a process for producing cores, a process for dip-coating and a process for combining boxes to cast. The invention comprises firstly, producing sand cores in a wood-made box which is composed of an upper half and a lower half, arranging sand cores which are produced into an iron slot which contains coating materials and dip-coating, reserving after drying, lastly, arranging the sand cores which are dip-coated with the coating materials on an upper sand box and a lower sand box, molding closely, and casting, finishing steps of cutting, hole-filling and wire-coning on a turning machine after polishing, and obtaining qualified protecting pipes of the thermocouples. The invention has the advantages that firstly, a plurality of common casting defects can be avoided and eliminated, finished product rate is increased from 70% to 95%, secondly, the preciseness of casts can be increased ...
