Abstract

The invention discloses a lightweight pouring flow-bearing combined pipe fitting and application thereof, belonging to the technical field of foundry equipment. The lightweight pouring flow-bearing combined pipe fitting is prepared from the following raw materials: 60-80 parts by weight of paper pulp, 20-30 parts by weight of a shaping agent and 3-8 parts by weight of a waterproof and dampproof agent; the paper pulp is prepared by adding waste paper and water into a pulper at a room temperature according to a weight ratio of 1: (10-20). When being used for foundry industry, the lightweight pouring flow-bearing combined pipe fitting does not make a reaction with molten metal. During pouring, the combined pipe fitting does not burst, and is non-sticky, slag-resistant and erosion-resistant. The refractoriness of the lightweight pouring flow-bearing combined pipe fitting reaches up to 1500 DEG C or above, so that the long-standing problem of sprue adhesion is solved.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to a lightweight pouring flow-bearing combined pipe fitting and its application. Background technique [0002] In modern casting technology and technology, the pouring process of molten metal has a great influence on the quality of casting products. The use of suitable runner products is to ensure that the technical indicators such as casting size, casting surface and internal quality meet the required quality of molten metal pouring process. key. [0003] The ceramic fiber sprue tube is a hollow tube made of mixed aluminum fiber as raw material by vacuum forming process, which is used to replace the sprue system composed of the traditional sand sprue cup and foam sprue. It is easy to install and use , can effectively reduce the probability of white spots and black spots in lost foam castings, thereby improving the quality of castings and casting efficiency, and improving...
