The invention provides a rice-made sponge cake and a processing method thereof. The rice-made sponge cake comprises the following ingredients in parts by weight: 100-180 parts of whole eggs, 60-70 parts of granulated sugar, 100 parts of rice flours, 1-1.5 parts of salt, 6-9 parts of vital gluten, o.5-2 parts of baking powders, 3-5 parts of cake oil, 10-15 parts of vegetable oil, and 20-35 parts of water. The rice-made sponge cake provided by the utility model has fine and smooth internal tissues, uniform air holes, spongy appearance, and no sour flavor, and is soft and elastic, and not easy to age.

The invention provides a casting-extrusion compound forming method for a magnesium alloy automobile wheel hub, which adopts a casting process to make a billet with a reasonable original structure and shape, and is characterized in that there are pre-forming, upsetting extrusion forming, isothermal extrusion, and fine shaping processes; wherein: casting After the billet and pre-forming, the pre-allocation required for the extrusion process that fills the mold cavity is left; the critical deformation control method is used to control the deformation degree, deformation rate and deformation temperature in the process of upsetting extrusion forming and isothermal extrusion. And control it within the scope of its permission; spray graphite lubricant in the mold. In order to prevent the grain growth caused by reheating and reduce the mechanical properties, the temperature of the forming blank gradually decreases with the increase of the process. The wheel hub produced by the method has fine crystal grains, good mechanical performance and surface quality. It is also suitable for use in the manufacture of other magnesium alloy ring and disc parts.

The invention discloses a casting method of a steering knuckle of nodular cast iron. The casting method comprises a mold manufacturing step, a sand mold manufacturing step and a pouring molding step, wherein the steering knuckle is vertically arranged, a thick part of a steering knuckle casting is arranged at the upper part, a thin-walled part of the steering knuckle casting is arranged at the lower part; a pouring system of the steering knuckle casting is divided into a pouring cup, a cross pouring gate and a straight pouring gate, the cross pouring gate is connected to the lower part of the pouring cup, the straight pouring gate is connected to the lower part of the cross pouring gate, and a scum riser is arranged at the bottom end of the straight pouring gate; the side wall of the straight pouring gate is connected with a first inner pouring gate, a second inner pouring gate and a third inner pouring gate from top to bottom; the steering knuckle casting is further provided with a hot riser, a cold riser and exhausting pieces; the sectional area ratio of each component of the casting is that F(straight pouring gate):F(cross pouring gate):F(inner pouring gates) is equal to 1:(1.2-1.4):(1.35-1.5); the casting is obtained by controlling the pouring temperature at 1370-1410 DEG C and carrying out pouring for 5-10 seconds. The casting method has the advantages that pouring speed is high, the defects such as shrinkage porosity, shrinkage cavity and the like cannot easily occur, and the casting is high in production efficiency, low in rejection rate and excellent in mechanical property.
